| titleOfInvention | Alginate beads for sustained release pharmaceutical delivery system using alginic acid and preparation method thereof |
| abstract | Alginic acid beet for sustained-release pharmaceutical delivery system of the present invention is composed of alginic acid, a structural material, and a medicinal active material, by mixing a structural material in an alginate aqueous solution to prepare an aqueous solution slurry, the desired pharmaceutically active substance in the aqueous solution slurry And mixing the slurry solution drop by drop into the polyvalent cation solution to cure, wash the cured beads, and dry the washed beads. The alginic acid beads prepared above are coated with an aqueous alginate solution to improve properties such as sustained release effect of the alginic acid beads, adsorption effect of heavy metals, and the like. The alginic acid beads prepared above were immersed in an aqueous alginate solution to give an alginate coating having a thickness of about 0.5 mm, and the coated alginic acid beads were injected into a polyvalent cation solution to cure the coating film, wash the cured beads, and wash the beads Alginic acid coated alginic acid beads are prepared by drying. Depending on the degree of effect desired, this coating process is repeated to produce multi-layer coated alginic acid beads. |
